What are the ovaries?

What are the ovaries?
Average rating: 4 out of 5 star rating

Women have two ovaries, one on either side of the uterus (womb) in the lower abdomen. Ovaries are small and round, each about the size of a walnut. The ovaries make eggs. In fertile women, each month an egg (ovum) is released from one of the ovaries. The egg passes down the fallopian tube into the uterus where it may be fertilised by a sperm.

The ovaries also make hormones including the main 'female' hormones - oestrogen and progesterone. These hormones pass into the bloodstream and have various effects on other parts of the body including regulating the menstrual cycle and periods.
